A Rapid Cu Enrichment Mechanism from Cu-Bearing Brine in Kuqa Basin, Xinjiang, China: Controlled by Crystallized Sequence of Saline Minerals

<div>SEM and EDS analysis of sample KC-G<sub>3</sub>. The upper left is a BSE image whereas the rest of the graphs are EDS spectrums. Gp: gypsum; Pa: paratacamite; HI: halite. The bright white mineral containing Pb and Cl might be PbCl<sub>2</sub>. The white mineral, containing Cu, Cl, O, and a few Si, Al, Ca, K, Pb, and Zn, is paratacamite (Cu<sub>2</sub> (OH)<sub>3</sub> Cl) and may contain clay minerals, Zn and Pb. The grey mineral containing Na and Cl is halite (NaCl). The ash black mineral containing Ca, S, and O is gypsum (CaSO<sub>4</sub>·2H<sub>2</sub>O).</div>
